Description

Changing mattress, winding device with such and use of these

The invention relates to a changing mattress according to claim 1, a winding device with such a claim 8 and the use of these according to claim 1. 1

From the prior art various changing pads for wrapping babies and toddlers are known. Cloths, thin mats and even thicker mattresses are used. However, mainly towels and mats are used outside the home because they can be transported better than mattresses.

The problem with all these variants is a winding on sloping and uneven

Underground, as it exists in particular on vehicle seats. Here, the child often rolls over the shoulder in the direction of the seat back when handling. The handling is correspondingly difficult, fails and leads to stress for parents and children. Many variants are difficult to clean and offer too little thermal insulation on cold surfaces.

The object of the invention is therefore to provide a device and its use, with which a child can be comfortably and easily wound in as many everyday situations. The device should also be easy to transport, compact to carry, easy to handle, thermally insulating and easy to clean.

Main features of the invention are specified in the characterizing part of claim 1 and claims 8 and 11. Embodiments are the subject matter of claims 2 to 7, 9 to 10 and 12 to 17.

The invention relates to a changing mattress having an upper side, a lower side, a first side boundary and a second side boundary, which face each other, and with a front end and a rear end, which are transverse to the first and second

Side boundary are aligned, wherein the front end in relation to the rear end has a taper.

The advantage of the taper according to the invention resides in the fact that the changing mattress can be laid well on a vehicle seat without the lying surface being excessively reduced. In the

Rejuvenation may for example be a side cheek of a seat back. The around the

Rejuvenation shortened first side boundary can then be attached to the backrest of the

Vehicle seat lie, that is, here is not a scratch, in which the baby could roll in. In another application, in particular if the coiling person does not have front access to the side of the vehicle seat, it is also possible to position the seatback in the taper and to align the changing mattress diagonally on the vehicle seat. Despite rejuvenation remains here also a large contact surface between the bottom and the vehicle seat, so that the changing mattress threatens to tilt from the seat. Of course, the changing mattress can also be used in places other than vehicle seats. The upper side preferably forms a flat lying surface. A reclining couch arises in soft execution alone by the laying on of the baby. Optionally, however, a reclining couch can be formed in the unloaded changing mattress. As a result, a role of the child is counteracted stronger. The underside should form a flat bearing surface. As a result, the changing mattress can be easily spread and used on all flat surfaces in everyday life. The First and second side boundary and the front and rear end frame the top and bottom or limit their extension.

An optional embodiment provides that the first side boundary and the second side boundary are aligned at least substantially parallel to one another. This results in a section with a constant width of the bed.

In a particular embodiment of the changing mattress, the taper is at least partially defined by a first blunt corner between the front end and the first one

Side boundary formed. Thus, a large bed surface can be provided, which is narrower only in the first blunt corner.

For the greatest possible flexibility with regard to the place of use, in particular also on vehicle seats or seats of passenger cars, there is a configuration in which the first blunt corner on the side of the front end exceeds 10% to 50%,

preferably over 20% to 45%, more preferably over 25% to 42%, and most preferably over 30% to 40% of the distance between the first and second

Side boundary extends. Also contributing to this is an embodiment according to which the first blunt corner on the side of the first page boundary is over 15% to 40%, preferably over 17% to 38%, more preferably over 20% to 35%, and most preferably over 25% extends to 30% of the distance between the front end and the rear end. Basically, the first blunt corner could be a concave or convex curve

exhibit. In a special design of the changing mattress, however, the first blunt corner is formed by an oblique first corner edge of the changing mattress. Such a particularly straight corner edge forms a stable contact surface, without a trough to the adjacent part as a seat back arises. In addition, the remaining lying area is large. Particularly preferably, the first corner edge is aligned at an angle between 35 degrees and 55 degrees, preferably between 40 degrees and 50 degrees and particularly preferably of 45 degrees to the first side boundary and to the front end or a front edge. Of the

Inside angle should be between 145 degrees and 125 degrees. An even greater flexibility with regard to the place of use is achieved with an optional embodiment of the winding mattress, wherein the taper is at least partially, in particular in addition to the first blunt corner, formed by a second obtuse corner between the front end and the second side boundary. Thus, the changing mattress can be used without restriction on both sides of a vehicle. The top and bottom can be made of different materials. The bottom, for example, have a higher slip resistance and / or higher robustness than the top. The upper side may in particular have a better cleanability and / or feel than the underside.

Because vehicle seats are usually constructed substantially symmetrical in the vehicle, there is a design in which the second blunt corner of the first blunt corner resembles.

In particular, the second obtuse corner on the front end side should be over 10% to 50%, preferably over 20% to 45%, more preferably over 25% to 42%, and most preferably over 30% and 40% of the distance between the Side boundaries or side edges extend. Furthermore, the second blunt corner on the side of the first page boundary should be over 15% to 40%, preferably over 17% to 38%, more preferably over 20% to 35%, and most preferably over 25% to 30% of the distance between extend the front end and the rear end. Optionally, the second blunt corner may be formed by an oblique second corner edge of the winding mattress.

Particularly preferably, the second obtuse corner is formed at least substantially mirror-inverted to the first obtuse corner.

In a special variant, the changing mattress has a flat collar, which the

Framed top and bottom. Such a frame provides protection for any thin sensitive skin of the first air chamber. In this case, the top and the bottom can be connected to each other in the collar, for example by gluing or welding. The collar should have a maximum width of 5.0 cm, preferably a maximum of 4.0 cm.

Furthermore, there is the option that hanger holes are formed in the winding mattress. With these, the changing mattress can be attached hanging for use or storage. Particularly suitable as an attachment site is the optional collar. That means that the

Are formed on hanging holes in the collar of the changing mattress. In practice, in particular, a design according to which the winding mattress is formed flat, preferably, the distance between the first and second

Side boundary or a side edge at least 5 times, preferably at least 7 times, and more preferably at least 10 times, the distance between the top and the bottom.

With regard to the application with a baby or a toddler and on a car seat, special absolute dimensions of the changing mattress prove to be particularly advantageous. In particular, the distance between the front end and the rear end should be between 40 cm and 90 cm, preferably between 50 cm and 85 cm, more preferably between 55 cm and 80 cm, and particularly preferably between 60 cm and 75 cm.

Furthermore, a dimensioning is appropriate in which the distance between the first and the second side boundary or side edge between 35 cm and 70 cm, preferably between 40 cm and 65 cm, more preferably between 45 cm and 62 cm, and particularly preferably between 50 cm and 60 cm.

In addition, absolute dimensions are advantageous in which the distance between the top and bottom is between 3.0 cm and 9.0 cm, preferably between 3.5 cm and 7 cm, and particularly preferably between 4 cm and 6 cm. As a result, a sufficient rigidity can be achieved with low packing or air volume.

According to an optional embodiment of the winding mattress, at least one first air chamber is arranged in the latter, wherein the winding mattress is stiffened with air when the first air chamber is filled. In the reverse case, the changing mattress is less stiff. In particular, the changing mattress is flaccid when the first air chamber is vented. The changing mattress should then have no inherent rigidity and is preferably collapsible. Thus, the changing mattress can be carried comfortably, because it is vented and compact. For ventilation and venting, the changing mattress should have a first air valve. This first air valve can open into the first air chamber. Preferably, the first air valve on the circumference of

Changing mattress arranged, in particular between the top and the bottom. Here it does not bother the lying baby nor does it make a bump on the underside. In addition, the easiest way to ventilate the valve is to use your mouth. To compensate for sloping ground, something can be placed under the stiff mattress to compensate for the slope. A full - surface relining is due to the rigidity of the Changing mattress not necessary. Another advantage of the first air chamber is the good thermal insulation of the child from the ground. Infections due to cooling are avoided.

The first air chamber may be a clean cavity that can be filled with air. That is, there are no unfolding agents available. This is very cheap. In a variant of

However, changing mattress has elastic unfolding means which exert a deployment force on the air chamber. Thus, the effort during inflation is at least partially reduced because the ventilation is at least partially without any action. The changing mattress should to a certain extent be a self-inflatable air mattress. Particularly preferably, an elastic foam is arranged in the air chamber. By optional longitudinal channels and / or transverse channels and / or vertical cavities, the volume of the foam can be kept low. The changing mattress 10 is thereby easily vented and collapsible. In addition, the changing mattress has a low transport weight. The invention also relates to a winding device with a winding mattress, a

Top, a bottom, a first side boundary and a second side boundary, which are opposite, and having a front end and a rear end, which are aligned transversely to the first and second side boundary, and with a

Straightening device with which the winding mattress is inclined over a geodetic

Subsoil is geodetic straight aligned. This ensures that the changing mattress forms a flat support for the baby, which therefore does not roll when handling. In principle, the changing mattress can be, for example, a flat body in the form of a rectangle with or without rounded corners, an ice, an oval or a combination of a rectangle and a semicircle.

In particular, the invention relates to a winding device with a winding mattress with

Rejuvenation at the front end as described above and below and one

Subsoil is geodetic straight aligned.

This also ensures that the changing mattress forms a flat support for the baby, which consequently does not roll when handling. For putting in the winding mattress is particularly flexible and good on car seats due to the taper. In one embodiment of the winding device, the straightening device has an air cushion, which is arranged on or below the underside of the winding mattress. An air cushion has the advantage that it can be easily adjusted in the thickness of the substrate by aerating or venting. It also compensates for unevenness in the ground due to air redistribution. For this purpose, the air cushion should have a second air chamber. Optionally, the thickness of the air cushion perpendiculular to the underside of the winding mattress by variable filling of the second air chamber with air adjustable. In practice, in particular, a design proves to be effective according to which the maximum thickness of the air cushion is between 4 cm and 20 cm, preferably between 8 cm and 18 cm, more preferably between 11 cm and 17 cm and particularly preferably between 12 cm and 16 cm , Such dimensioning achieves compatibility with most vehicle seats. For airing and bleeding, the air bag should have a second air valve. This second air valve can open into the second air chamber. Preferably, the second air valve opens at the periphery by the length and width in the second air chamber, in particular between a pillow top and a pillow bottom. Here, the second air valve does not form any rub on the pillow top and pillow bottom. For putting in the second air valve can be easily achieved with the mouth to inflate. Optionally, on the circumference of the air cushion between the

Pillow top and the pillow bottom is a pillow collar is formed, which the

Cushion top and the pillow base framed. The pillow top and the

Cushion bottom can be connected together in the pillow collar. In addition, the winding device is particularly flexible, if the air cushion is not on the

Changing mattress is attached. Rather, it should be laid loose.

For a stable support of the changing mattress dimensioning is optimal, in which the maximum thickness of the air cushion, in particular between the pillow top and a pillow bottom, is smaller than the length of the air cushion. This is also helped by the optional dimensioning, according to which the maximum thickness of the air cushion is smaller than the width of the air cushion. Variable on an uneven surface such as a vehicle seat, an air cushion can be arranged, in which the width of the air cushion is smaller than the length of the

Air cushion. In practice, an absolute size of the air bag, in which the maximum length of the air cushion between 20 cm and 55 cm, preferably between 25 cm and 50 cm, more preferably between 30 cm and 46 cm and more preferably between 35 cm and 43 cm is. In addition, a design, according to which the maximum width of the air cushion between 8 cm and 25 cm, preferably between 10 cm and 24 cm, proves itself, more preferably between 12 cm and 23 cm, and more preferably between 13 cm and 22 cm.

Also in relation to the size of the winding mattress dimensions are advantageous. Thus, the maximum thickness of the air cushion should be greater than the distance between the top and bottom of the winding mattress. The changing mattress thus remains compact and with the air cushion relatively large unevenness or gradient in the ground can be compensated. In addition, the length and the width of the air cushion should be less than the distance between the first and the second side boundary of the winding mattress. This allows in particular a good insertion of the air cushion in a vehicle seat having side cheeks on the seat and / or on the backrest.

The optional arrangement of the air cushion below the underside of the winding mattress can be done differently. In one variant, the air cushion is loose, that is, without coupling agent on the winding mattress. As a result, the air cushion can be positioned freely to the changing mattress. In a second variant, the changing mattress and the air cushion are connected via detachable coupling means. For example, buttons, hook-and-loop fasteners or zippers are suitable. Slippage of the air cushion below the winding mattress is avoided. In a third variant, the air cushion is firmly connected to the changing mattress. Optionally, the air cushion and the changing mattress are made in one piece. This variant is inexpensive.

For example, the air cushion can then be folded under the changing mattress.

Because different or independent air pressures are required to the goals of a stiff changing mattress and a set thickness of the air cushion are required, there is an embodiment in which the air cushion and the winding mattress each having separate air chambers and separate air valves. That is, the first air chambers and the second

Air chambers have no gas-permeable connection. For putting in, this means that the first air valve and the second air valve are different. Optionally, the first and / or second air chamber each consist of a plurality of sub-chambers, either via

Flow connections are connected or each having its own valve.

Preferably, the air valves are automatically closing or closed with the mouth, in particular by applying pressure. Thus escapes after reaching air pressure and before closing the valve no air. Particularly advantageous is a one-way turning valve. In the first orientation only filling with air is possible here. As a result, no air escapes when settling the mouth. In turned orientation, only one air outlet should be possible. This allows the air to squeeze well and the air chamber does not fill up again when handling. If the reversing valve is not seated in a receptacle provided for this, air can flow freely through the receptacle. Can be supplemented such a reversing valve with a closure means. Then the air pressure in the air chamber will last for a longer period of time. The one-way reversing valve is particularly suitable for combination with deployment means.

In a particularly comfortable and easily transportable embodiment, the air cushion forms a packing chamber for the changing mattress. The air cushion can therefore accommodate the winding mattress for transport. For this purpose, a closable packing opening in the second

Open air chamber. Optionally, the packing opening is rollable. By rolling in accordance with a waterproof bag (wet bag), the packing opening can close and is sufficiently airtight at least for a winding process. For wrapping and packaging of the winding device, a closing belt should be arranged along the packing opening. This can be opened and closed quickly with the help of an optional buckle. Thus, the packing opening can be opened and closed quickly.

In another variant, the pillow front side or the back of the pillow is double-walled with inner wall and outer wall formed in the outer wall a packing opening and formed in the space between the inner wall and the outer wall a packing space.

According to an optional embodiment of the winding device, the

Straightening on a tether, which is fixed to a headrest of a vehicle. This allows the changing mat to hang over the sloping seat.

For this purpose, the tether should be fixable or fixed to the changing mattress. Preferably, the tether is fixed or fixed to the optional suspension holes in the changing mattress. For a simple attachment and removal of the tether on the changing mattress, the tether should have hooking means, in particular hooks.

The winding device can be supplemented by the imprint of a user manual on the air cushion and / or the changing mattress. The working steps are preferably depicted in sequence. Furthermore, the invention relates to a use of a winding mattress as described above and below or a winding device as described above or

described below is for wrapping a baby or toddler. The use of comfortable winding without stress for the winder and the child to be wrapped in a variety of everyday environments is possible. The risk of contamination is minimized.

In an optional use case of the winding device, the use is made on a vehicle seat of a vehicle. The first blunt corner allows a flexible and good support of the changing mattress on the vehicle seat and it can be realized depending on the optional design options of the changing mattress or the winding device and the other advantages of the above description.

A special use variant provides that a side cheek of a backrest of the vehicle seat in the taper, in particular in the first blunt corner or

Eckausnehmung, and the first and second side boundary are aligned longitudinally to a front seat edge of a seat surface of the vehicle seat or to the vehicle axle. Thus, the child is easily accessible on easily accessible vehicle seats on the changing mattress.

In another use variant, it is provided that a middle part of a backrest of the vehicle seat in the taper, in particular in the first blunt corner or

Eckausnehmung, and the first and second side boundary are aligned diagonally to a front seat edge of a seat surface of the vehicle seat or to the vehicle axle. This is particularly advantageous if only an oblique access by position and

Opening angle of the vehicle door to the vehicle seat is possible. The lying child can be aligned by the diagonal orientation of the changing mattress perpendicular to the winder.

An optional supplement to the use is that in the winding mattress at least a first air chamber is arranged, wherein the winding mattress is stiffened by filling the first air chamber with air. Thus, the changing mattress is transferred from a well-stowable state in the operating condition. On a level surface complete ventilation may be unnecessary. On uneven ground, however, the child is much more comfortable with an inherent rigidity of the changing mattress.

The use can be supplemented by the fact that the winding device a

Straightening device, with the winding mattress over a geodesic oblique Ground is aligned geodetically straight. This effectively prevents the child from unintentionally moving on a sloping surface on the changing mattress. It therefore does not need to be recorded. The hands are therefore more for the actual

Winding task available.

In a special use it is provided that the straightening device

Air cushion, which is or is disposed on or below the underside of the changing mattress, and / or has a tether, which is fixed to a headrest of a vehicle, wherein a geodetic orientation over the geodesically inclined ground by adjusting the amount of air in the air cushion below the Changing mattress and / or by setting the tether above the winding mattress and adjusting the length of the tether takes place. This compensates for a slope on the vehicle in a simple manner and the changing mattress forms a horizontal support. For this purpose, the air cushion in the

Seat recess lie between lateral elevations of the seat or side cheeks. Here it can at least partially fill the recess and the changing mattress on the

Support the air cushion. In addition, the changing mattress can rest partially on the lateral elevations or the side cheeks. As a result, it is additionally stored stable.

Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. Show it:

Fig. 1 1 is a side view of the arrangement shown in Fig. 9.

FIG. 1 shows a perspective view of a changing mattress 1. This changing mattress 1 is additionally shown in a plan view in Fig. 2 and in a side view in Fig. 3. In Figs. 1, 2 and 3 it can be seen that the winding mattress 10 has a top 1 1 (only in Figs. 1 and 3 to see), a bottom 12, a first and a second side boundary 13, 14 which are opposite and and a leading edge 15 (only seen in FIGS. 1 and 2) and a trailing end 16 and trailing edge, respectively, which are aligned transversely of the first and second side boundaries 13, 14 , having. The upper side 1 1 forms a flat lying surface and the underside 12 a flat support surface.

In the winding mattress 10, a first air chamber 30 is arranged, whereby the winding mattress 10 is rigid when filling the first air chamber 30 with air L. If the first air chamber 30 is vented, the winding mattress 10 is limp. It then has no rigidity and can be merged. For ventilation of the first air chamber 30, a first air valve 31 opens into the first air chamber 30. The first air valve 31 is at the periphery of

Changing mattress 10 disposed between the top 1 1 and the bottom 12. The

Changing mattress 10 is embodied here as a self-inflatable air mattress in that elastic unfolding means 32 in the form of an elastic foam, which exert a deployment force on the air chamber 30, are arranged in the first air chamber 30. Through longitudinal and transverse channels or vertical cavities, the volume of the foam can be kept low. The changing mattress 10 is thereby easily ventilated, easy to fold and light.

Furthermore, the changing mattress 10 has a flat collar 22, which framed the top 1 1 and the bottom 12. The top 1 1 and the bottom 12 are connected to each other in this collar 22, in particular welded or glued. As can be seen in FIGS. 1 and 2, suspension holes 21 are formed in the collar 22.

Overall, the changing mattress 10 is flat. The distance A1 between the first and second side boundary 13, 14 is at least 5 times, preferably at least 7 times and particularly preferably at least 10 times the distance A2 (see FIG. 3) between the upper side 11 and the bottom 12. In absolute values amounts to the distance A3 between the front end 15 and the rear end 16 is between 40 cm and 90 cm, preferably between 50 cm and 85 cm, more preferably between 55 cm and 80 cm, and particularly preferably between 60 cm and 75 cm. For putting in the distance A1 between the first and the second side boundary 13, 14 between 35 cm and 70 cm, preferably between 40 cm and 65 cm, more preferably between 45 cm and 62 cm, and particularly preferably between 50 cm and 60 cm.

1 and 2 is between the front end 15, in particular a front edge, and the first side boundary 13, a first obtuse corner 17 and a first

Eckausnehmung formed by an oblique corner edge 19. As a result, the front end 15 is tapered relative to the rear end 16. The first blunt corner 17 extends on the side of the front end 15 over a length of between 10% and 50%, preferably between 20% and 45%, more preferably between 25% and 42%, and most preferably between 30% and 40%. the distance A1 between the first and second side boundary 13, 14. For putting, the length of the first blunt corner 17 on the side of the first

Side boundary 13 between 15% and 40%, preferably between 17% and 38%, more preferably between 20% and 35%, and most preferably between 25% and 30% of the distance A3 between the front end 15 and the rear end 16. Presently the first corner edge 19 forms an angle of 45 degrees to the first side boundary 13 and to the front end 15 and the front edge, respectively. The interior angle is therefore 135 degrees.

In addition, a second obtuse corner 18, which is similar to the first obtuse corner 17, is formed between the front end 15 and the second side boundary 14 by means of a second corner edge 20. This also provides a taper on the side of the front end 15 opposite the rear end 16. In the present case, the second blunt corner 18

mirrored to the first blunt corner 17 formed. This refers in particular to the collar 22. In contrast, the first air chamber 30 is slightly asymmetrically shifted so that the collar 22 is wider at the first side boundary 13 than at the second

Side boundary 14. The suspension holes 21 can be found in the wider collar portion on the side of the first side boundary 13th

FIG. 4 shows a perspective view of an air cushion 51

Straightening device 50, with which the winding mattress 10 according to FIGS. 1 to 3 is geodetically straight aligned over a geodetically inclined ground. The air bag 51 has a pad top 54 and a pad bottom 55. At the periphery of the air bag 51, there is a pad top 54 and pad bottom 55

Cushion collar 56 is formed, which framing the cushion top 54 and the cushion bottom 55. The pillow top 54 and the pillow bottom 55 are connected together in the pillow collar 56, in particular welded or glued.

The air cushion 51 also has an air chamber 52 (hereinafter referred to as the second

Air chamber 52 denotes), in which a second air valve 53 opens. The second air valve 53 is arranged in particular on the circumference by the length D2 and width D3 and is here between the top surface 54 and the cushion bottom 55. Thus, the thickness D1 of the air cushion by variable filling of the second air chamber 52 is adjustable with air. This is the

Air cushion 51 stabilized by the pillow collar 56. The maximum thickness D1 of the air cushion

51 is between 4 cm and 20 cm, preferably between 8 cm and 18 cm, more preferably between 1 1 cm and 17 cm and particularly preferably between 12 cm and 16 cm. In addition, the maximum thickness D1 of the airbag 51 is smaller than the length D2 and the width D3 of the airbag 51. The width D3 of the airbag 51 is again smaller than the length D2 of the airbag 51.

In absolute terms, the maximum length D2 of the air bag 51 is between 20 cm and 55 cm, preferably between 25 cm and 50 cm, more preferably between 30 cm and 46 cm and particularly preferably between 35 cm and 43 cm. In addition, the maximum width D3 of the air bag 51 is between 8 cm and 25 cm, preferably between 10 cm and 24 cm, more preferably between 12 cm and 23 cm and particularly preferably between 13 cm and 22 cm.

Comparing the dimensioning of the air cushion 51 with that of the winding mattress 10 according to FIGS. 1, 2 and 3, it can be seen in particular in FIGS. 5 to 11 that the maximum thickness D1 of the air cushion 51 is greater than the distance A2 between the top side 1 1 and the bottom 12 of the winding mattress 10. In addition, the length D2 and the width D3 of the

Air cushion 51 is less than the distance A1 between the first and the second

Side boundary 13, 14 of the winding mattress 10.

The air cushion 51 and the winding mattress 10 thus each have a separate air chamber 30,

52 and separate air valves 31, 53 on. The first air chambers 30 and the second air chamber 52 have no gas-permeable connection. In addition, the first air valve 31 and the second air valve 53 are different. 5 shows a perspective view of a tether 60 designed as

Straightening device 50. This can be used alone or in combination with the designed as an air cushion 51 straightening device 50 of FIG. 4 to a

Changing mattress 10 according to FIGS. 1 to 3 over a geodesically inclined ground geodesically straight. In particular, such a tether on a headrest 102 of a vehicle can be set to the mattress 10 to store at least one side hanging. For the tether 60 is fixed to the winding mattress 10,

in particular by means of hook-shaped hooking means 61 at the two free ends of the tether 60. These can be defined in the hanging holes 21 in the changing mattress 10 by hanging.

In Figs. 6 to 11 can be seen, as with a winding device 1 having a

Changing mattress 10 according to FIGS. 1, 2 and 3 and a straightening device 50 comprising an air cushion 51 according to FIG. 4 and a tether 60 according to FIG. 5, a geodesic straight

Lying surface on an uneven surface U in the form of a vehicle seat 101 is created.

With regard to the winding mattress 10 shown in FIGS. 6 to 11, reference is made to the above description of FIGS. 1 to 3. For putting in mind, with regard to the air bag 10, reference is made to the above description of FIG. 4 and, with regard to the tether 60, to the above description of FIG. 5.

Beyond the item description, it can be seen in Fig. 6 to 1 1, the relative arrangement of winding mattress 10, air cushion 51 and tether 60 to each other.
